Hi Tobias, Here is something I acquired from this mailing list some years ago. It works well for me:
#---run in previous version (e.g. R 3.1.0) packages <- installed.packages()[,"Package"] save(packages, file="Rpackages_R3.1.0") #---run in new version load("Rpackages_R3.1.0") for (p in setdiff(packages, installed.packages()[,"Package"])) install.packages(p) Hope this helps.

Is there something similar to R? If not, isn't it quite easy to write? For me, it would be much easier to work on projects with other people if I could just install all dependencies with one line in a generalised manner. Did anybody try something like that before me?
